Osseous surgery is designed to modify and reshape deformities in the alveolar bone surrounding the teeth. It is a common requirement in effective treatment of more involved periodontal diseases. In some instances, the bony support of the tooth assumes an unusual configuration as a result of uneven progression of the disease. When this occurs, modification of the altered bone support may be indicated. This surgical procedure is used to smooth/correct defects and irregularities in the bone surrounding the diseased teeth with the ultimate goal of reducing or eliminating the periodontal pockets.
